Chock this one up to science being used for good and not evil. A team of historians, curators and forensic anthropologists have concluded that our very first First Lady was not the droopy double-chinned frump we previously thought. She was a hottie! Using a computerized age-regression portrait, they peeled away the wrinkles and revealed a slim, sexy, brunette Helen-Hunt lookalike in her 20s. No wonder Washington killed so many Redcoats and crossed the Delaware. He had to get home to America’s first pinup girl.
